  • Patent number: 6586366
    Abstract: Oil based emulsifiable concentrates include (a) at least one oil component; (b) at least one surfactant hydrocarboxyl saccharide, particularly a surfactant hydrocarbyl polysaccharide (HPS); and (c) at least one other non-ionic surfactant. The concentrates are typically homogeneous for at least 24 hours and emulsify readily on dilution into water. The concentrates preferably also include: (d) an antifoaming agent, especially a polysiloxane; and/or (e) at least one chemical agent specific to the intended use of the composition, such as an agrochemical, especially a herbicide, or a metal corrosion inhibitor. The concentrates can be diluted readily in water to give emulsion formulations which can be sprayed onto substrates, e.g. when the chemical agent is a herbicide, onto weeds.

  • Patent number: 6583101
    Abstract: Hard floor finishes and other stubborn soils can be removed using an aqueous dispersion of an alkylene glycol phenyl ether solvent combined with an ether alcohol solvent/coupler. Each component is used at a concentration that result in the creation of a visible dispersed appearance of the aqueous dilute use solutions. We have found that the alkylene glycol phenyl ether, in combination with at least one ether alcohol coupler or solvent, interacts with the aqueous medium to surprisingly provide enhanced cleaning performances. Hard to remove soils such as highly crosslinked urethanes and acrylic materials can be solubilized and removed by the alcohol solvent dispersions of the invention. We have found that the alkylene phenyl ether solvent requires a specific coupler cosolvent for activity. Such activity can be enhanced by the presence of a second coupler cosolvent and the use of a specific class of nonionic surfactant materials.

  • Patent number: 6544942
    Abstract: A pseudo-stable phase-splitting solvent composition that forms a single liquid phase when subjected to mild agitation and retains that single phase while the composition is applied to a surface, but which forms two or more laminar liquid phases promptly after being applied. A concentrated solvent film forms on the surface, under a film containing the other phase. The solvent preferably is denser than water, and the composition preferably is diluted with water. This enables the solvent to attack the surface at near full strength, and provides a water seal over the solvent film. The solvent composition can be used full strength or in diluted form for cleaning, reducing the microbial population of, or degreasing a variety of surfaces, and for stripping a variety of difficult-to-remove coatings from surfaces.

  • Publication number: 20020132750
    Abstract: The present invention may include a cleanser having a liposome and greater than about 40 weight percent of a solvent. The liposome may be loaded with the solvent more than about 7 days after the manufacture of the liposome. The solvent may be an isoprenoid or ester solvent. Furthermore, the solvent may be d-limonene or a dibasic ester. In addition, the liposome may be selected from the group consisting of large unilamellar vesicles, multilamellar vesicles, paucilamellar vesicles, and small unilamellar vesicles. Desirably, the liposome is a paucilamellar vesicle. Desirably, the cleanser may have a solvent weight percent greater than about 60. More desirably, the cleanser may have a weight percent of solvent greater than about 80. Moreover, the solvent is about a 1:1 weight ratio of d-limonene and dibasic ester.

  • Patent number: 6426326
    Abstract: The invention relates to liquid cleansing compositions in lattellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. However, these liquids often undergo an irreversible decrease in viscosity under freeze/thaw conditions, losing their moisturization signals. The use of low salt levels in amphoteric and anionic surfactants in a structured liquid product has been found to improve its freeze/thaw stability.
